v @ther obj ect-s andadvantagesj reside in 'cerkthe Arevolving platformof acraneequipped With a `Winch inl accordance With-the presentinvention, parts being omittedifor the-sakes of illustration; and vFigure 2 is a view in vertical section on line 2 2 of vFigure l,parts'being'omitted and parts being shown in section 'for the Isakeofsimplicity inillustration. 'm Referring to the draWings,` numeral ldesignates the usual combi/nedy svving-geana'nd roller pathwhich isyrigidlysecured-to fthe usualsub-fraine (not sho-Wn) fastened to thetruck or trailer in accordance With the usual"-h practice. Ati-evolvingframeor platform 2 is supported for vrotation yon thecOmbined swing-gearand roller :path l `in thel usual manner.

For the dual purposeof constraining'therevolving frame 2 tofk rotationabouta fixed vertical axis and-also for affordingal mounting for the 'Winch construction or` attachment to be hereinafter more' fully-de'scribed,fa 'hollow gudgeon pin 3 is interfitted with they `frames land 2, this pin being suitabletted in an opening 4 -prov-idedfin theframe l1 and in va bushing 5j liningan opening G-formed in vtherevolving` `frame 2. The lower end fiange 7 abutting the frame 1 underthe action of a capstan nut construction S which coacts with the upperend of the gudgeon pin 3.

A power plant which may be an internal combustion engine 10 is supportedon the revolving frame 2 and the engine shaft has a pinion 11 whichmeshes with a gear wheel 12 fixed to one end of a jack shaft 13.Oppositely disposed beveled gears 14 are mounted onthe shaft 13 and areselectively clutched thereto by cone clutches 15. These beveled gears111 constantly mesh with a beveled gear 16 fixed to the upper end of avertical shaft 17 journaled in bearings provided therefor on theplatform 2 and having a spur pinion 18 which meshes with an intermediategear wheel 19 loosely mounted on a vertical swing shaft 2() rotatablysupported in bearings provided on the revolving frame 2 and carrying apinion 21 which constantly meshes with the fixed swing-gear 1. The gear19, though Y rotatable on the shaft 20, may be'clutched .clearance isalso available.

thereto by means of a sliding clutch member 22 splined on the shaft 20and having teeth 23 adapted to interlock or intermesh with teeth 24@aformed on a cooperable clutch membe-r 24 secured to the gear wheel 19.Suitable operating mechanism is provided for the lvarious clutches, theoperating mechanism for the clutch member 24 being` designated at C.

By suitably manipulating the clutches 15 and sliding the clutch member22 to intermesh the teeth 23 and 24C, the revolving frame 2 may be swungin one direction or the other.

A vertical winch sh aft 25 is rotatably fitted in the hollow gudgeon pin3 and projects above the upper end of the gudgeonvpin for a substantialdistance. A winch head 26 is suitably fixed to the upper end of thiswinch shaft 25. lnterposed between the winch head 26 and the upper endof the gudgeon pin 3 and fixed to the winch shaft 25, is a winch drivinggear 27, this gear 27 constantly meshing with the intermediate gear 19of the gear- ,ing which swings the revolving frame 2.

`With this construction the winch head is located at the axis ofrotation of the revolving frame and this relation of the winch head tothe revolving frame makes it possible to utilize the winch head to pullin any direction regardless of the position of the crane and with therevolving platform positioned as may be desirable. Of course, therevolving platform may be and frequently is rotated to present the bestclearance in the direction of pull to prevent fouling of the winch rope.ln this connection it is to be understood that forwardly of the winchhead there is a wide clearance for the winch rope. Some lateral Therevolving` platform may be `swung in either direction. with facility butit is often inconvenient and undesirable to move the entire crane.Movement of the entire crane is never necessary with applicantsconstruction. The swinggear for revolving the frame is cut out ordisconnected from the reversingv clutch arrangement on the jack shaft bysuitably manipulating the clutch member 22 and this is done when thewinch head is to be rotated.

The winch head is rotated in either direction by selecting` the properclutch 15. It is to be noted that in any position of the revolvingplatform the winch head may be rotated in either direction. The winchconstruction or attachment is extremely simple and involves, inconnection with the novel swinggear shown, merely the provision of ahollow gudgeon pin, the shaft 425, winch head 26, and gear 27, and theorganization of these elements with the crane structure as hereinaboveset out and as shown in the accompanying drawings.

While the winch, when provided, is a permanent part of the craneequipment, it is an attachment in the sense that it is auxiliary oraccessory equipment. Nevertheless, the

winch furthers the crane operations and in contributing to this singleresult, the winch coacts with the swing-gearing which rotates therevolving platform.

The invention claimedl is 1. A winch attachment for use with a cranehaving a stationary and a revolving frame and a hollow gudgeon pinconstraining the revolving frame to rotation on the fixed frame, andcomprising a shaft rotatably supported in the hollow gudgeon pin, awinch headl fixed to said shaft above the gudgeon pin, a gear wheelconn-ected to said shaft between the winch and the adjacent end of thegudgeon pin, and means cooperable with the gear wheel' for rotating thesaid shaft and winch in either direction. 1

2. A. winch attachment for use with a crane having a stationary and arevolving frame, a hollow gudgeon pin constraining the revolving frameto rotation on the xed frame, and clutch controlled gearing for swingingthe revolving frame in either direction, and comprising a shaftrotatably supported in the hollow gudgeon pin, a winch head fixed to theupper end of said shaft, and a gear wheel fixed to the winch shaftbetween the winch head and the gudgeon pin and meshed with the clutchcontrolled gearing whereby the winch parts may be rotated `in eitherdirection in any position of the revolving frame.

3. A winch attachment for use with a crane having a stationary andarevolving frame, means constraining the revolving frame to rotation onthe fixed frame and clutch controlled gearing for rotating the revolvingframe in either direction, and comprising a mountingsupporting the winchfor rotation about said means as'an axis, a rotatable winch head on saidmounting, and a gear' wheel intereonneeted with the Winch head so as toconstrain the winch head to rotate therewith, said gear Wheelintermeshing With said clutch controlled gearing and being driventhereby, whereby the Winch head may be rotated in either direction inany position of the revolving frame.

In Witness whereof, I hereto affix lny signature.
